The present invention relates to the general` class of implements orappliances of the hand operated type for applying liquid coatings, andmore specically to 'an improved self-dispensing roller for applyingpaint of the fountain roller and web class, which' while well adaptedfor applying varnish,` enameLand other liquidcoatings to buildingstructures, Iwill hereinafter'be referred to as an applicator 'forliquid paints."

The primary object of the invention is the provision of amanually'operated implement of this character that is composed of aminimum number of parts thatV may with facility be manufactured with alow costof production, the component parts may be assembled'vvithconvenience,

to constitute a unitary structure-'that may be` manipulated easily toapply'auniformly smooth coating with `a minimum expenditureof timeandlabor.y a i l The invention consists in certain novel features ofconstruction and combinations and arrangements of parts involving arotary reservoir 'or roller and its supporting handle-frame as willhereinafter be described in detail and more particularly pointed outY inthev appended claim.

In thev accompanying v drawings We have illustrated a complete exampleof a physical embodiment of our invention in which the parts arecombined and arranged in accord with one mode we have devised for thepractical applicationof the principles of.. the invention. It willhowever be understood that changes t'and-v alterations, are

contemplated and may be made in these exempliiying drawings andmechanical structures, within the scope of our claim, without departingfrom the principles of the invention.

Figure 1 is a plan view of an applicator involving our invention, partof the web or porous cover being broken away to disclose thedistributing ducts and ports of the rotary reservoir or roller.

Figure 2 is a sectional end view as at line 2 2 of Fig. l.

Figure 3 is a sectional View on the line 3-3 of Figure 6.

Figure 4 is an enlarged detail sectional view of the roller as at line4-4 of Fig. 1.

Figure 5 is a detail sectional View showing one of the exterior ductsand a port of the roller.

Figure 6 is a longitudinal sectional view of the implement together withits supporting handleframe.

Figure 7 is a transverse sectional View at line 1-1 of Fig. 6; andFigure 8 is a transverse sectional view at line 8 8 of Fig. 6.

Figure'9 is a sectional detail View of the adjustable handle.

` Figure 10 is a fragmentary detail View showing the means forpreventing longitudinal displacemerit of the "journal for the rollers;and Figure 1l is"`aV transverse sectional view at line II--I--IofFig.10.` 3- I In carrying out our invention-we employ a rotaryreservoir in the nature of ar tubular or cylindrical roller I,preferably of molded plastic material, having a closed end 2 integralthere with,l and ahead `3 of similar material, or .other suitablematerial, and the head is provided with an annular beveled flange 4 thatfits over a cornplementary beveled edge 5 of the roller to insure asealedjoint. y,

The exterior surface of the roller is provided with a series of equallyspaced right hand spiral grooves 6, and a complementary series ofequally spaced left hand spiral grooves 'lthat intersect,

Vand the intersections' of these grooves or distributing ducts arefashioned with orices or ports 8 to insure an equalized distribution ofthe liquid paint from the interior of the roller, or reservoir, throughthe ports. and thence through the networkof ducts to an enclosing web orporous cover 9 of the roller. 'f l a a j yIn its initial form, the `webor ,cover is an 'absorbent rectangular mat, of porous material that isadapted to be permeated or impregnated lwith `the liquid paintl from thenetwork of ducts,` and the mat is Wrapped around thecylindrical rolleras a cover, and in the form of a4 cylindrical tube.

For securely uniting the porous web with the roller the latter isprovided with an inner longitudinally extending rib II] that forms anexterior joint groove II, and the adjoining ends I2 of the mat arefirmly pressed into the groove to form an attaching bead rrnly embeddedin the groove, and presenting a smooth exterior surface for the web orcover.

The ends of the tubular cover may be retained on the exterior of theroller, as by means of annular groove threads I3 that are equally spacedfrom each other and extend circumferentially of the roller. The groovesI3 also tend to seal the ends of the roller to prevent the paint fromflowing out of the grooves 6 and 1 over the outer ends of the roller.

The reservoir formed within the hollow roller may be lled or replenishedwith liquid paint through a lling hole I4 in the head 3 of the roller,and the filling hole is closed by means of a tapered plug I5 that isfrictionally held in thewalls of the lling hole.

to receive one end of a tubular bearing or `sleeve l 2|, the other endof which is threaded and-screwed into complementary threads of thebushing I1. A

For mounting the bearing sleeve in the recessed boss 2U the end of thesleeve is threaded to receive the threads of a lock 1nut 22 which Yhas ahead 23 for use with a wrench or other tool, and

a packing ring 24 is employed in the recessed boss `toseal the .jointagainst leaks from the interior of the reservoir.

. The roller is equipped with a handle frame of special design thatincludes an end piece 25 'enclosed within and extending the l'ength ofthe bearingsleeve, which forms a journal bearing for the bearing sleeveao'out'vvhich the roller revolves as the implement is manipulated acrossthe surfao'eto be painted. -fIo prevent longitudinal dis- .placement ofthe journal bearing, or the handle frame, the journal 25 is Vprovidedwith an annular .groove 26 in which is mounted a split ring 21 locatedbetween an end ofthe 'sleeve and within the Anut 22; and the nut; whichtightens the cap or head 3 on the roller, also securely mounts thejournal in its bearing sleeve.

AAs best seen in Figs. 1 and 6, the handle-frame, in addition to thejournal 25 also includes a return-bend yoke 28, and an arm 29 parallelwith the journal 25, vand this arm terminates in an integral shank 30disposed radially of the roller.

An adjustablesleeve 3l having internal threads ltoreceive thethreadedend of the shank, is also provided with external threads formounting a handle 32 rigidly on the sleeve, and it will be apparent thatthe handle may be adjusted on the threaded shank Yto lengthen or shortenthe support for the handle as the roller or Vapplicator is reciprocatedfor 'applying 'the "liquid `coating to a surface.

Q As the roller is manually reciprocated, or stroked, over a desiredsurface, and with the porous Web in contact therewith, the roller re- 4volves upon its journal bearing, and the liquid paint is fed from theinterior reservoir through the ports and the net-Work of ducts, andthence through the porous web or cover, for uniform and equaldistribution of the paint to assure a smooth and even painted surface.

Instead of retaining the: ends of.- the tubular cover on the exteriorofthe rollferaspreviously described, drawstrings 33 may be used so thatthe cover is removable, and can be easily removed and replaced asdesired.

f `Having thus `fully described our invention, what "We claim as new anddesire to secure by Letters Patent isa,

In a fountain applicator for liquid paint, the combination with asupporting handle frame including Ya 'journaLfof a cylindrical rollerhaving a porouspad and an interior reservoir, means for feeding liquidpaint from the reservoir to the inner surface of the .porous pad, saidroller having tubular end-bosses formed on the interior surface of theends of s'aid roller "centrally thereof, a

Ybushing mounted i'nofnejboss, a bearing sleeve extending through the'reservoir and surrounding the journal and Vhaving one end threadablyconnected-to said bushing, a lo'ck nut located in the other bosssurrounding th'e""j`o`urnal and 'threaded on the sleeve, and'means forretaining the'journal against longitudinal displacement.
